Description
One, technical field
The utility model relates to the process units of organic chemical products biodiesel (being fatty acid methyl ester), is specifically related to continuous rectification apparatus for biological diesel oil.
Two, background technology
The biodiesel distilling apparatus is generally the batch process distilling apparatus, the batch process distilling apparatus mainly is made up of distillation still, destilling tower and condenser, during production crude fatty acid methyl ester to be distilled is added in the distillation still, by heating separated biodiesel and mink cell focus, biodiesel gets finished product after cooling, mink cell focus is discharged from distillation still; Batch process distilling apparatus production biodiesel exists following defective:
1. it is higher to contain the low carbon fatty acid methyl esters in the biodiesel of Sheng Chaning, has reduced Cetane number and two the capability and performance indexs of calorific value in the biodiesel.
2. the Separation of Fatty Acids in the biodiesel is not thorough, and grease decomposes easily, causes the acid number of biodiesel higher, and color and luster is dark, influences product quality.
3. batch process distilling apparatus utilization rate of equipment and installations is low, and the energy consumption height is of poor quality, influences the product recovery rate.
Three, summary of the invention
The continuous rectification apparatus for biological diesel oil that energy consumption was low, product purity is high, quality good, utilization rate of equipment and installations is high, recovery rate is high when the purpose of this utility model provided a kind of production of biodiesel.
For realizing above purpose, the utility model continuous rectification apparatus for biological diesel oil comprises the preceding condenser of vavuum pump, feed pump, flash column, rectifying column, reboiler, circulating pump, condenser and vavuum pump, and described rectifying column is the above rectifying column of two-stage; Flash column bottom overflow pipe is connected with the heat cycles pipeline of first order rectifier bottoms, and prime rectifier bottoms overflow pipe is connected with the heat cycles pipeline of back level rectifier bottoms; Every grade of rectifying column all is furnished with the circulation heating facility of band circulating pump and reboiler, and is furnished with condenser; The rectifying thing output channel of drawing from rectifying columns at different levels enters storage tank through behind the heat exchanger, and coarse biodiesel input channel and the convection current of rectifying thing output channel are through heat exchanger; The final stage rectifier bottoms is provided with the mink cell focus overflow pipe.
Owing to contain impurity such as low amounts of water, methyl alcohol, lower boiling ester, ethers in the unrectified biodiesel, under vacuum state, removed from flash column; Because of different its boiling point difference of fatty acid methyl ester of phosphorus content, by the reboiler that the uses the utility model various heat exchange area heating that circulates, the different boiling fatty acid methyl ester respectively from rectifying columns at different levels continuous rectification come out, remaining mink cell focus is also discharged from the overflow pipe of afterbody rectifier bottoms continuously; The utility model has also adopted the high vacuum facility, can reduce the boiling point of biodiesel, avoided because high temperature causes problems such as cracking, oxidation, the color and luster of biodiesel deepen, and capable of reducing energy consumption, realized the effective separation between moisture content, different phosphorus content fatty acid methyl ester, the mink cell focus preferably.The low carbon fatty acid methyl esters can be used for the living beings industrial chemicals, as the higher aliphatic acid methyl esters Cetane number height of biodiesel, calorific value is big, acid number is low, constant product quality.In addition, this appliance arrangement utilization rate height, processing ease, steady quality, energy consumption is low, and the product recovery rate improves greatly.
Four, description of drawings
Fig. 1 is the utility model continuous rectification apparatus for biological diesel oil schematic diagram.
Five, specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
The utility model continuous rectification apparatus for biological diesel oil shown in Figure 1 comprises the preceding condenser 1 and 9 of feed pump 13, flash column 2, rectifying column, reboiler, circulating pump, condenser and vavuum pump, connect vavuum pump behind the condenser 1 and 9 before the vavuum pump, described rectifying column comprises rectifying column 5 and 6 two-stages, flash column 2 bottom overflow pipes are connected with rectifying column 5 bottom cycle water backs, and the overflow pipe of rectifying column 5 bottoms is connected with rectifying column 6 bottom cycle water backs; Rectifying column 5 is furnished with the circulation heating facility and the condenser 14 of band circulating pump 11 and reboiler 4, and rectifying column 6 also is furnished with the circulation heating facility and the condenser 15 of band circulating pump 12 and reboiler 8; The rectifying thing output channel of drawing from rectifying column enters storage tank through behind the heat exchanger 7, and coarse biodiesel input channel and the convection current of rectifying thing output channel are through heat exchanger 7, and rectifying column 6 bottoms are provided with the output of mink cell focus overflow pipe.
During operation, feed pump 13 enters flash column 2 after 7 heat exchanges of coarse biodiesel input heat exchanger are heated up, and heats through reboiler 3 circulations under circulating pump 10 effects, steam low boiling impurities such as water, methyl alcohol, ester, ethers under vacuum state, output is collected after condenser 16 condensations; A small amount of vapour-liquid of taking out of when vacuumizing is collected after condenser 1 and 9 condensations before vavuum pump to avoid entering vavuum pump; Remaining material (being mainly biodiesel) builds up to overflow pipe and enters rectifying column 5 bottom cycle water backs from flash column 2 bottoms, under circulating pump 11 effect through reboiler 4 circulations add thermal rectification go out in the low carbon fatty acid methyl esters; Remaining material builds up to overflow pipe and enters rectifying column 6 bottom cycle water backs in rectifying column 5 bottoms, add thermal rectification through reboiler 8 circulations and go out medium high carbon fatty acid methyl ester (biodiesel) under circulating pump 12 effects; Residue is a mink cell focus, discharges from the overflow pipe of rectifying column 6 bottoms; Biodiesel is collected through condenser 14,15 condensations respectively after rectifying column 5 and 6 outputs; After cooling off by heat exchanger 7, collects the product of rectifying output; Can reduce the color and luster and the control free acid value of biodiesel by the reflux ratio of regulating rectifying column.
